Definitions
- the present invention relates to the field of creating a pathway into an animal. More particularly, the present invention relates to more effective methods and apparatus for safely creating pathways in mammals for applications such as artificial insemination (Al).
- Al artificial insemination
- FIGS. 1A and IB show conventional Al catheters for swine.
- the rigid deep insemination catheters are pushed and/or threaded through cervical canals using bulbous ends or slight angles on their tips in an attempt to navigate the curves and turns of the cervical canal.
- One inherent flaw of these rigid deep insemination catheters is their hard tips that can easily damage or puncture soft tissue areas during entry and exit procedures, often injuring or even killing the animal.
- Other disadvantages of these rigid catheters include the need for a professional, such as veterinarian or a highly trained technician, to perform these trans-cervical intra-uterine Al procedures, which reduces but does not substantially eliminate the risk of serious trauma and resulting sterility or death.
- a method and apparatus for safer and more effective deep trans-cervical intra- uterine artificial insemination is provided.
- Such a deep Al catheter causes minimal discomfort and risk of trauma, and does not require the services of a highly trained Al professional
- a catheter is inserted into the cervical tract of the animal to begin creating a pathway in the reproductive tract of an animal.
- a membrane initially positioned inside a tube section of the catheter, is extended from an opening in the tube and into the tract under pressure. The membrane extends into the tract without friction, i.e. without sliding action between the membrane and the tract, thereby reducing the discomfort and the risk of trauma or injury to the animal.
- pressure causes the tip of the membrane to open thereby releasing the Al fluid and depositing the genetic material suspended in the fluid into the reproductive tract.
- deployment of the membrane is facilitated by its taper.
- tapering can be accomplished by reducing the wall thickness and/or diameter of the membrane towards its tip.
- other applications for the pathway include other therapeutic, diagnostic or procedures, such as introducing fluoroscopic cameras, instruments, and drug delivery. Note that the various features of the present invention, including the extending membrane and the nozzle, can be practiced alone or in combination.
- FIGS. 1A and IB are exemplary conventional Al catheters.
- FIG. 2A, 2B and 2C show deep rigid deep insemination catheters extending from conventional Al catheters.

- FIGS. 5 A, 5B and 5C show one embodiment of the catheter attached to two exemplary Al dispensers.
- FIGS. 5D and 5E show the catheter during and after deployment.
- FIG. 6 is an enlarged drawing of one embodiment of a tapered nozzle for the catheter.
- FIGS. 7 A through 7E show the insertion and deployment of the catheter in a sow.
- FIGS. 8A, 8B and 8C are cross-sectional views of alternative embodiments of the membrane for the catheter.

- FIGS 14A through 14E show another herniating embodiment of the membrane of the present invention.
- FIGS 15A and 15B show yet another embodiment of the invention where the membrane has a closed tip.
- FIGS. 16A and 16B show another embodiment of the invention wherein a container is coupled to a nozzle.
- Figures 3 A and 3B are views of one embodiment of catheter 300, prior to and after deployment of a membrane.
- Figures 4A through 4F illustrate the assembly of catheter 300 of Figures 3 A and 3B.
- Figures 4A, 4B and 4C show a membrane 410, a catheter tube 420, and a subassembly 430 comprising membrane 410 and tube 420.
- Membrane 410 can be attached to catheter tube 420 by inserting tip 418 of membrane 410 into opening 421 of tube 420, until deployable sections 414 and 416 of membrane of 410 are inside hollow 424 of tube 420.
- a leading edge 412 of membrane 410 is snapped into a positioning ring 422 located on the outer surface of catheter tube 420, as shown in Figure 4C.
- Positioning ring 422 can be machined or molded depending on the manufacturing process.
- Other chemical and/or physical means of attaching membrane 410 to tube 420 can also be used, e.g., adhesive, heat bonding, ultrasonic welding, chemical bonding or heat staking.
- subassembly 430 can be press fitted into catheter nozzle 440, by engaging membrane edge 412 of subassembly 430 into an internal positioning ring 442 of nozzle 440.
- subassembly 430 can be sufficiently mechanically coupled to nozzle 440, the various components of assembled catheter 300 can be further secured to each other by sonically welded or heat staked to prevent separation during deployment, such as inside the reproductive tract during artificial insemination
- subassembly 430 can be replaced by a one-piece membrane-tube combination that can be manufactured by, for example, blow molding.
- Another method for constructing subassembly 430 is to insert catheter tube 420 over a membrane die, similar to dies used in balloon manufacturing, dipping the die and the attached catheter tube 420 into a suitable liquid membrane media until the entire die and about half inch of the end of catheter tube 420 is coated with the membrane media. After the liquid membrane media is cured, membrane tip 418 is cut. A downward movement of catheter tube 420 detaches tube 420 from the die and also automatically inverts membrane 410 into catheter tube 420, thereby forming subassembly 430.
- Membrane tip 418 can include an opening such as a slit or a circular or oval hole. Alternatively, instead of an opening, tip 418 can include a soluble plug or a pre-weakened seal designed to dissolve or fail under pressure at the right time.
- nozzle 440 can be of different shapes and sizes, and combination thereof, including but not limited to spirals, bulbous knobs, including the nozzles illustrated by Figures 1A, IB, 2A, 2B, and 2C. Although spirals are optional, approximately one to three spirals may be optimal when catheter 300 is used in swine. Shorter nozzles are also possible because membrane 410 is self-sealing, longer and self-guiding. In some embodiments, nozzle 440 is tapered to aid in insertion into the tract.
- nozzle 440 may have a smaller diameter and shorter length. Conversely, for second to seventh parity sows with larger birth canals, nozzle 440 may have a larger diameter and longer length to facilitate the deposit of genetic materials and/or diagnostic instruments.
- the overall length of membrane 410 can be approximately four to eight inches and tapering gently from one- eighth of an inch.
- Suitable materials for nozzle 440 and membrane 410 of catheter 300 include silicone, silicone gel packs, foam, latex, ClearTexTM (available from Zeller International, New York), polymers, plastics, metals, or combinations thereof.
- Other candidate materials include the polyolefins, polyethylene and polypropylene, the polyacetals, ploy-butadiene-styrene copolymers, the polyfluoro and polyfluorochloro-polymers, such as TeflonTM and other polymers and copolymers.
- catheter 300 may have multiple tubes with multiple membranes. Such an embodiment may be useful in laparoscopy where one pathway is created for a camera and a second pathway is created for an instrument during surgery. Alternatively, a large diameter catheter 300 can also be used to create a large pathway within which one or more smaller catheters can be deployed.
- Figures 5A, 5D, and 5E show catheter 300, before, during and after deployment, respectively.
- Figures 5B and 5C one embodiment of the catheter attached to two types of Al dispensers.
- Figures 7 A through 7E show the insertion and deployment of catheter 300 in a sow 780.
- Catheter 300 is deployed by introducing genetic material suspended in a suitable fluid under pressure into sow 780.
- the Al fluid can be transported in a suitable dispenser, such as a squeeze bottle 560 or a prepackaged tube 570.
- catheter 300 is inserted into vaginal cavity 782 of sow 780.
- Catheter 300 is gradually pushed further into sow 780 until nozzle tip 556 is fully inserted into vagina cavity 782, as shown in Figure 7B.
- catheter 300 is then gently eased into cervical tract 784 of sow 780 until nozzle tip 556 engages at least the first cervical ring of cervical tract 784.
- membrane 410 is not advanced until catheter 300 is positioned in cervical tract 784, thereby preventing contaminated materials that may be contained in vaginal cavity 782, or fluids from cervical tract 784, from being accidentally transferred into uterus 788 or uterine horns of sow 780. Hence, bio-security of uterus 788 is maintained.
- Al fluid under pressure is fed into catheter 300.
- Pressure can be generated manually via a dispenser 560 or by a suitable pump, such as a pneumatic or hydraulic pump.
- the effect of the pressure causes membrane 410 to begin unfolding in an inside-out manner not unlike removing one's sock by pulling from the open end.
- catheter 300 includes an opening in membrane tip 418, the Al fluid under pressure keeps the opening of tip 418 closed until membrane 410 is fully extended into cervical tract 784.
- membrane 410 of catheter 300 continues to advance in a frictionless manner into the curved and narrow passageway of cervical tract 784, automatically centering the ever-expanding forward most portion of membrane 410 in the direction of least resistance. It is this expansion and automatic centering action of membrane 410 that advantageously enables membrane 410 to worm its way through cervical tract 784 without damaging or irritating delicate tissues.
- membrane tip 418 is near to or at the entrance of uterus 788, the pressure causes tip 418 to open thereby allowing the Al fluid to be deposited at the deeper end of cervical tract 786 and/or directly into uterus 788.
- membrane 410 aids deployment in cervical tract 786, the taper may not be necessary for proper deployment. In some applications, partial penetration of membrane 410 into the uterine horns (not shown) is also possible, allowing for example the introduction of embryo transplants.
- the invention eliminates the need for multiple removable sheaths by progressively feeding new portion of membrane 410 in an unfolding process. Every newly extended portion of membrane 410 is sterile because there is no prior contact with other biological tissue, such as vaginal cavity or other body fluids.
- membrane 410 collapses after the fluid pressure dissipates, allowing for safe and easy withdrawal of the relatively flat, flexible, smooth and lubricated surface of membrane 410, causing minimal discomfort and posing minimal risk of trauma and damage to the recipient animal.
- trans-cervical intra-uterine Al advantageously reduces the volume of Al fluid needed for successful insemination by delivering the genetic materials where nature intended, i.e., into uterus 788. For example, a normal dose of 4-6 billion fresh swine semen may be reduced to fewer than 1 billion for successful Al when trans-cervical intra-uterine Al is employed.
- catheter 300 is effective during refractory heat, which is the much longer period during estrus when cervical tract 784 is relaxed, allowing easier penetration of cervical tract 784. Since catheter 300 bridges cervical tract 784 and deposits the genetic material suspended in the Al fluid much closer to uterus 788, resistance caused by clamping cervical tract 784 during standing heat is not needed and probably undesirable. Hence catheter 300 is effective during the much longer refractory heat period because semen can be deposited efficiently and with minimal restriction in cervical tract 784. Hence the advantages of trans-cervical intra-uterine Al can be combined with the relative safety and effectiveness of catheter 300 of the present invention. farmers can now use Al in the much longer refractory heat period, allowing these swine farms to operate more efficiently, since successful Al is no longer limited to the much shorter standing heat period.
- Yet another significant advantage of the present invention is the ability of membrane 410 to deploy in a self-centering and self-directing manner, when deployed under pressure.
- a suitable lubricant may be applied to the surface of membrane 410 that may come into contact with the tract of the animal, further reducing discomfort and risk of trauma during deployment and withdrawal of catheter 300.
- membrane 410 may have a fairly large diameter. This is because if the diameter is too small, membrane 410 may get trapped in the nooks and crannies between protrusions from the wall of cervical tract 784, 786. A fairly large diameter allows membrane 410 to gently push aside these protrusions thereby permitting membrane 410 to complete deployment.
- tube 420 has a flared hollow section 424a and a reduced hollow section 424b.
- the flared aspect for tube 420 can be manufactured using techniques known to one skilled in the art including extrusion with vacuum or air pressure, blow- molding, and injection molding.
- Figures 10 and 11 illustrate alternate embodiments of catheter tube 420 where a larger diameter tube section 420a is coupled to a smaller diameter tube section 420b. These sections 420a and 420b can be mated using techniques known to one skilled in the art such as press-fitting, adhesive or heat sealing, or with a connector 420c as shown in Figure 11.
- FIGS 12A-12C show the assembly of a self-sealing nozzle 1240 for catheter 1200, whereby the inner diameter of nozzle 1240 is tapered and is configured to fit securely thereby forming a tight seal with subassembly 430 when subassembly 430 is inserted into nozzle 1240.
- Figures 12D & 12E show the assembly of a snap-on version the self- sealing nozzle 1240 of Figures 12A-12C.
- membrane 410 in accordance with another aspect of the invention, as shown by Figure 13 A, deployment of membrane 410 through any obstructions such as a narrowing of cervical tract 784, 786 is facilitated by its tapered shape. Tapering of membrane 410 can be accomplished by reducing the wall thickness and/or diameter of membrane 410 towards its tip, i.e., away from nozzle 440. Hence, in some embodiments, the membrane wall thickness is tapered while the membrane diameter is gently tapered or not tapered at all.
- the length of membrane 410 is approximately 3 to 7 inches from nozzle 440 to membrane tip.
- the external diameter of membrane 410 can range from about 3/16 inches to 5/16 inches.
- Membrane wall thickness can vary from approximately 0.025 inches at nozzle 440 to 0.003 inches at the membrane tip.
- membrane dimensions will depend on the properties of membrane material such as elasticity and strength, and also depend on the size of the tract of the targeted animal species.
- Suitable membrane materials include a latex compound (product code 1175YL, batch X2471) available from Heveatex Corporation in Fall River, Massachusetts.
- Suitable coagulants include calcium nitrate tetra-hydrate crystal reagent, Ca(NO3)2.4H20.
- FIGs 13B through 13E illustrate the controlled herniation aspect of the present invention which is made possible by tapered membrane 410.
- membrane encounters an obstruction in the cervical tract 784.
- herniation occurs at the point of least resistance, which is at the furthermost point of deployment in the cervical tract 784, i.e., the furthest point from nozzle 440.
- the herniation clears the obstruction at tract 784, enabling membrane 410 to deploy toward cervical tract 786.
- membrane 410 encounters another obstruction at cervical tract 786 and herniates at the present furthermost point of deployment, cervical tract 786, thereby clearing the obstruction and enabling membrane 410 to complete deployment into uterus 788.
- membrane 410 with a tapered wall thickness there are several ways to manufacture membrane 410 with a tapered wall thickness.
- One way is to dip a membrane tool with the nozzle end first into a tank of liquid latex (not shown). By controlling the dwell time and dipping cycle in the tank, membrane 410 with a graduated wall thickness can be formed over the membrane tool. The combination of gravity and because the nozzle end of the membrane tool is the first to enter the tank and is also the last portion to leave the tank ensures that the wall thickness of membrane 410 is thickest near the nozzle end.
- membrane 1410 herniates substantially continuously and uniformly along the tract during deployment.
- This embodiment may be useful in animals with relatively complex reproductive tracts, such as ewes, where the cervical tract comprises many potential traps for membrane 1410.
- membrane 1410 fills the cervical tract and these traps can be gently pressed aside and rendering a relatively smooth pathway for the incoming genetic material.
- FIG. 15A and 15B show another embodiment of the invention where membrane 1510 has a closed tip 1512.
- This closed tip 1512 enables the substantially precise placement of embryo(s) suspended in a minimal amount of fluid, or gel deposited at membrane pouch 1514.
- This embodiment may also be useful for depositing a small volume of genetic material such as previously frozen semen.
- a container 1610 e.g. a bottle or flexible semen tube (570), which holds the genetic material, can be inserted into the vagina of the animal.
- nozzle 440 attached to membrane 410, can be screwed directly onto container 1610 and the completed assembly 1600 is ready for deployment.
- catheter 300 Once fully extended into a tract of a recipient animal, e.g., into the reproductive tract, respiratory tract, circulatory tract or digestive tract, catheter 300 provides a protective shield for the insertion of devices such as endoscopes, tracheal tubes, or other diagnostic and therapeutic instruments.
- Membrane 410 (the original patent references #416, unless I am misinterpreting7) shields the tract from the scraping, scarring and discomfort caused by the contact and friction of the hard, semi-blunt instruments and probes on the otherwise unprotected tract. As a result, healing time and the risk of infection are significantly reduced, thereby lowering recovery time and cost.
- catheter 300 uses an inverted membrane 410 which is turned inside-out during deployment, the concepts of a self-guiding, frictionless, membrane 410 which is deployed with minimal discomfort and trauma to recipient animals has many applications.
- catheter 300 can also be used for diagnostic and/or therapeutic applications in which pathways are created in the reproductive tract, respiratory tract, circulatory tract or digestive tract of the recipient animal or a patient. These pathways enable procedures such as embryo transplant and drug delivery to be performed. Laparoscopic procedures such as introducing cameras and instruments are also possible.
- the size and shape of catheter 300 may vary.
